Peanut Allergy Clinical Trial
— PROTECTOfficial title:
A Phase I Clinical Trial to Evaluate the Safety and Tolerability of VLP Peanut in Healthy Subjects and Subjects With Peanut Allergy and to Explore Preliminary Signals of Its Efficacy (PROTECT)
This phase I clinical trial is designed to evaluate the safety and tolerability of VLP Peanut in healthy subjects and in subjects with peanut allergy (PA). This clinical trial will evaluate the immunotoxicity profile of VLP Peanut in healthy subjects and assess the immunotoxicity profile and the degree of reactogenicity (allergenicity) in subjects with PA. This clinical trial will also explore preliminary proof of efficacy of VLP Peanut in subjects with PA.

Unable to receive epinephrine therapy or at greater risk of developing adverse reactions after epinephrine administration as assessed by the site Investigator. 8. Clinical history of drug or alcohol abuse, which, in the Investigator's opinion, could interfere with the subject's ability to participate in the clinical trial. 9. Participation in a clinical research trial with any investigational drug/placebo within 3 months of screening (Visit 1) or concomitantly with this clinical trial. 10.
